TRUSS-BRACE FOR WAGON-AXLES.

To (allw/wm it may concern-.-

Be it known that I, I/VINFIELD 0.1VIANN, a citizen of the United States, residing in Des Moines, county of Polk, and State of Iowa, have invented a new and useful Improvement in Truss-Braces for Wagon-Axles, of which the following is a specification.

The object of my invention is to provide 'a means of strengthening and equalizing the load of a wagon-axle.

A further object is to provide a means of securely joining the sand-board and axle or bolster and axle, as the case may be, in such a manner as to add the additional strength of the sand-board or bolster to the axle.

A further object is to construct such a means in a simple, strong, durable, and inexpensive manner.

My invention consists of certain details of construction hereinafter set forth, pointed out in my claim, and illustrated in the accompanying drawings, in which Figure I shows a front elevation view of the sand-board and front axle of a wagon fitted out with my improved device. Fig. IIshows a rear elevation of the rear bolster and axle of a wagon provided with my truss-brace. Fig. III shows a plan View of a gearing of a wagon fitted out with my improved device. Fig. IV shows a detail view of one of the plates, and Fig. V shows a plan view of the cap-plate I employ.

Referring to the accompanying drawings, the reference-numeral 10 is used to indicate the front axle of a wagon, and the numeral 11 the sand-board mounted thereon. The sand-board I employ is designed to be of sufficent length to provide for each of its ends projecting over a portion of the hub of the wheel, said ends being hollowed from their under surfaces for this purpose.

Mounted on the upper surface at each end of the sand-board llis a cap-plate 12 and 13, respectively, said cap-plates being provided on each of their longitudinal sides with a lug 14 and 15, respectively. Extending downwardly from the upper surface on each of the lugs 14 and 15 is an inclined plane, and extending through the central portion of said lugs at right angles to the inclined surface is an orifice 16 and 17, respectively, designed for purposes hereinafter set forth.

The numerals. 18, 19, and 20 indicate plates secured to the under portion of the axle, the plate 19 being centrally located and the plates 5 5 18 and 20 being located near the ends of the axle. These plates are of a sufficient length to provide for their ends projecting beyond the sides of the axle for purposes hereinafter set forth. 6

The numeral 21 indicates one of the bracerods I employ, said rod being screw-threaded on each of its ends. One end of the said rod is passed through the orifice 16 in the lug 1 and a nut screwed on its end. The rod ex- 5 tends downwardly from the lug on a plane inclined at right angles to the plane of the inclined surface of the said lug to the under surface of the axle, where it engages the projecting lug 18. From this lug 18 the rod 7 passing under the lug 19 extends to the opposite side of the axle, where it engages the lug 20, and is curved upwardly, its end finally passing through the orifice 17 in the lug 15, where it is secured by means of a nut being screwed onto the end.

The rod 22 is designed as a companion brace, and is exactly similar to the rod 21 in every respect, and is secured to the rear portion of the sand-board and axle in exactly the same manner as the rod 21 just described.

The numeral 23 indicates a U-shaped bolt designed to engage the sand-board and axle at a point near the wheel and to rigidly secure the said two pieces together, and the numeral 3 5 24 indicates a like U-shaped bolt designed to perform a like service at the opposite end of the sand-board and axle.

The rear axle of the wagon and the rear bolster are provided with a pair of brace- 9 rods, cap-plates, and lug-plates and U-shaped bolts in exactly the same manner as the front sand-board and front axle, and the ends of the rear bolster are also hollowed as are the ends of the front sand-board.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

-' A truss-brace for wagons comprising in combination a bolster hollowed in its under fi l? 800,928

surface at each of its ends; a cap-plate 0n ranged and combined substantially as and for whlicb arelniounted llugs1 each of Which is prothe purposes stated.
